具体实施方式Detailed ways
现在将参考附图更全面地描述示例实施例。然而，示例实施例能够以多种形式实施，且不应被理解为限于在此阐述的范例；相反，提供这些实施例使得本公开将更加全面和完整，并将示例实施例的构思全面地传达给本领域的技术人员。图中相同的附图标记表示相同或类似的结构，因而将省略它们的详细描述。Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the present disclosure will be more comprehensive and complete and will fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.
用语“一个”、“一”、“所述”用以表示存在一个或多个要素/组成部分/等；用语“包括”和“具有”用以表示开放式的包括在内的意思并且是指除了列出的要素/组成部分/等之外还可存在另外的要素/组成部分/等。The terms "a", "an", and "the" are used to indicate the presence of one or more elements/components/etc.; the terms "comprising" and "having" are used to indicate an open-ended inclusive meaning and mean that additional elements/components/etc. may be present in addition to the listed elements/components/etc.
如图1所示，为本公开显示面板一种示例性实施例的结构示意图。该显示面板可以包括显示区AA，以及位于显示区AA为扇出区FT。该显示面板还包括衬底基板、多条数据线Da、第一数据扇出线Fa1、第二数据扇出线Fa2。其中，数据线Da位于所述显示区AA，且数据线Da在衬底基板上的正投影沿第一方向X间隔分布且沿第二方向Y延伸，第一方向X和第二方向Y可以相交，例如，第一方向X可以为行方向，第二方向Y可以为列方向。第一数据扇出线Fa1位于所述扇出区FT，所述第一数据扇出线Fa1在衬底基板上的正投影可以沿第二方向间Y隔分布且沿所述第一方向X延伸，第一数据扇出线Fa1与所述数据线Da对应设置，第一数据扇出线Fa1连接与其对应的所述数据线Da。第二数据扇出线Fa2位于所述扇出区FT，第二数据扇出线Fa2在所述衬底基板上的正投影沿第一方向X间隔分布且沿第二方向Y延伸，第二数据扇出线Fa2与所述第一数据扇出线Fa1对应设置，所述第二数据扇出线Fa2连接与其对应的所述第一数据扇出线Fa1。本示例性实施例提供的显示面板将扇出区设置于显示区，避免了在边框区设置扇出区，从而可以降低显示面板下边框和下边角区域的面积，即可以实现窄边框设置。As shown in FIG1 , it is a schematic diagram of the structure of an exemplary embodiment of the display panel of the present disclosure. The display panel may include a display area AA, and a fan-out area FT located in the display area AA. The display panel also includes a substrate, a plurality of data lines Da, a first data fan-out line Fa1, and a second data fan-out line Fa2. Among them, the data line Da is located in the display area AA, and the orthographic projection of the data line Da on the substrate is distributed along the first direction X at intervals and extends along the second direction Y. The first direction X and the second direction Y may intersect, for example, the first direction X may be a row direction, and the second direction Y may be a column direction. The first data fan-out line Fa1 is located in the fan-out area FT, and the orthographic projection of the first data fan-out line Fa1 on the substrate may be distributed along the second direction Y at intervals and extend along the first direction X. The first data fan-out line Fa1 is arranged corresponding to the data line Da, and the first data fan-out line Fa1 is connected to the corresponding data line Da. The second data fan-out line Fa2 is located in the fan-out area FT, and the orthographic projection of the second data fan-out line Fa2 on the substrate is spaced along the first direction X and extends along the second direction Y. The second data fan-out line Fa2 is arranged corresponding to the first data fan-out line Fa1, and the second data fan-out line Fa2 is connected to the first data fan-out line Fa1 corresponding thereto. The display panel provided by this exemplary embodiment arranges the fan-out area in the display area, avoiding the arrangement of the fan-out area in the frame area, thereby reducing the area of the lower frame and the lower corner area of the display panel, that is, a narrow frame arrangement can be achieved.
如图1所示，分隔线XX将显示区AA分隔成在第一方向X上分布的两个显示区。远离分隔线XX一侧的数据线Da通过第一数据扇出线Fa1连接靠近分隔线XX一侧的第二数据扇出线Fa2。扇出区FT可以包括第一扇出区FT1和第二扇出区FT2，第一数据扇出线Fa1位于第一扇出区FT1，第二数据扇出线Fa2位于第二扇出区FT2。第一扇出区FT1可以包括第一子扇出区FT11和第二子扇出区FT12，第一子扇出区FT11和第二子扇出区FT12位于第二扇出区FT2在第一方向X上的两侧。As shown in FIG1 , the separation line XX separates the display area AA into two display areas distributed in the first direction X. The data line Da on the side away from the separation line XX is connected to the second data fan-out line Fa2 on the side close to the separation line XX through the first data fan-out line Fa1. The fan-out area FT may include a first fan-out area FT1 and a second fan-out area FT2, the first data fan-out line Fa1 is located in the first fan-out area FT1, and the second data fan-out line Fa2 is located in the second fan-out area FT2. The first fan-out area FT1 may include a first sub-fan-out area FT11 and a second sub-fan-out area FT12, and the first sub-fan-out area FT11 and the second sub-fan-out area FT12 are located on both sides of the second fan-out area FT2 in the first direction X.
应该理解的是，在其他示例性实施例中，第一数据扇出线Fa1和第二数据扇出线Fa2还可以有其他设置方式。例如，靠近分隔线XX一侧的数据线Da通过第一数据扇出线Fa1连接靠近分隔线XX一侧的第二数据扇出线Fa2；或，远离分隔线XX一侧的数据线Da通过第一数据扇出线Fa1连接远离分隔线XX一侧的第二数据扇出线Fa2。再例如，第一数据扇出线Fa1的长度还可以自上边框向下边框方式逐渐增加。It should be understood that in other exemplary embodiments, the first data fan-out line Fa1 and the second data fan-out line Fa2 may also be arranged in other ways. For example, the data line Da on the side close to the dividing line XX is connected to the second data fan-out line Fa2 on the side close to the dividing line XX through the first data fan-out line Fa1; or, the data line Da on the side away from the dividing line XX is connected to the second data fan-out line Fa2 on the side away from the dividing line XX through the first data fan-out line Fa1. For another example, the length of the first data fan-out line Fa1 may also be gradually increased from the upper frame to the lower frame.
本示例性实施例中，显示面板在扇出区FT增设有第一数据扇出线Fa1和第二数据扇出线Fa2，扇出区FT以外的显示区没有设置第一数据扇出线Fa1和第二数据扇出线Fa2。由于第一数据扇出线Fa1和第二数据扇出线Fa2具有反光和遮光作用，显示面板在息屏状态下，显示面板的扇出区和其他显示区具有不同的反光和透光效果，从而导致显示面板出现暗影。In this exemplary embodiment, the display panel is additionally provided with the first data fan-out line Fa1 and the second data fan-out line Fa2 in the fan-out area FT, and the display area outside the fan-out area FT is not provided with the first data fan-out line Fa1 and the second data fan-out line Fa2. Since the first data fan-out line Fa1 and the second data fan-out line Fa2 have the functions of reflecting and shielding light, when the display panel is in the screen-off state, the fan-out area and other display areas of the display panel have different reflecting and light-transmitting effects, thereby causing a dark shadow to appear on the display panel.
基于此，本示例性实施例还提供另一种显示面板，如图2所示，为本公开显示面板另一种示例性实施例的结构示意图。该显示面板可以包括多条第一信号线H1，多条第二信号线V2。其中，第一信号线H1位于所述显示区AA，所述第一信号线H1在所述衬底基板上的正投影沿所述第一方向X延伸且沿所述第二方向Y间隔分布，多条所述第一信号线H1中包括第一子信号线H11、第三模拟线Dm3。所述第一子信号线H11包括间隔设置的第一数据扇出线Fa1和第一模拟线Dm1；第三模拟线Dm3位于所述第一扇出区FT1以外的显示区AA。第二信号线V2位于所述显示区AA，且第二信号线V2与所述第一信号线H1位于不同导电层，所述第二信号线V2在所述衬底基板上的正投影沿所述第二方向Y延伸且沿所述第一方向X间隔分布，多条所述第二信号线V2中包括第二子信号线V22和第四模拟线Dm4。所述第二子信号线V22包括间隔设置的第二数据扇出线Fa2和第二模拟线Dm2；第四模拟线Dm4位于所述第二扇出区FT2以外的显示区AA。Based on this, this exemplary embodiment also provides another display panel, as shown in FIG2, which is a schematic diagram of the structure of another exemplary embodiment of the display panel disclosed in the present invention. The display panel may include a plurality of first signal lines H1 and a plurality of second signal lines V2. Among them, the first signal line H1 is located in the display area AA, the orthographic projection of the first signal line H1 on the substrate extends along the first direction X and is spaced along the second direction Y, and the plurality of first signal lines H1 include a first sub-signal line H11 and a third analog line Dm3. The first sub-signal line H11 includes a first data fan-out line Fa1 and a first analog line Dm1 arranged at intervals; the third analog line Dm3 is located in the display area AA outside the first fan-out area FT1. The second signal line V2 is located in the display area AA, and the second signal line V2 and the first signal line H1 are located in different conductive layers, the orthographic projection of the second signal line V2 on the substrate extends along the second direction Y and is spaced along the first direction X, and the plurality of second signal lines V2 include a second sub-signal line V22 and a fourth analog line Dm4. The second sub-signal line V22 includes a second data fan-out line Fa2 and a second analog line Dm2 which are arranged at intervals; and a fourth analog line Dm4 is located in the display area AA outside the second fan-out area FT2.
如图2所示，本示例性实施例通过增设第一模拟线Dm1、第二模拟线Dm2、第三模拟线Dm3、第四模拟线Dm4，从而可以使得整个显示区AA中信号线的密度接近一致，从而解决了上述暗影的技术问题。需要说明的是，当第一数据扇出线Fa1和第二数据扇出线Fa2以其他方式分布时，本公开也可以通过增设模拟线的方式消除上述暗影。As shown in FIG2 , this exemplary embodiment adds a first analog line Dm1, a second analog line Dm2, a third analog line Dm3, and a fourth analog line Dm4, so that the density of the signal lines in the entire display area AA is close to the same, thereby solving the technical problem of the above-mentioned dark shadows. It should be noted that when the first data fan-out line Fa1 and the second data fan-out line Fa2 are distributed in other ways, the present disclosure can also eliminate the above-mentioned dark shadows by adding analog lines.
本示例性实施例中，多条所述第一信号线H1可以位于同一导电层，多条所述第二信号线V2可以位于同一导电层；所述第二信号线V2所在导电层可以位于所述第一信号线H1所在导电层背离所述衬底基板的一侧。例如，第一信号线H1可以位于显示面板的第一源漏层，第二信号线V2可以位于显示面板的第二源漏层。此外，数据线Da也可以位于显示面板的第二源漏层，第二信号线V2在所述衬底基板上的正投影可以位于相邻两所述数据线Da在所述衬底基板上的正投影之间。In this exemplary embodiment, a plurality of the first signal lines H1 may be located in the same conductive layer, and a plurality of the second signal lines V2 may be located in the same conductive layer; the conductive layer where the second signal lines V2 are located may be located on the side of the conductive layer where the first signal lines H1 are located away from the base substrate. For example, the first signal line H1 may be located in the first source-drain layer of the display panel, and the second signal line V2 may be located in the second source-drain layer of the display panel. In addition, the data line Da may also be located in the second source-drain layer of the display panel, and the orthographic projection of the second signal line V2 on the base substrate may be located between the orthographic projections of two adjacent data lines Da on the base substrate.
应该理解的是，在其他示例性实施例中，第一信号线和第二信号线也可以位于其他导电层，例如，第一信号线还可以位于显示面板中的第一栅极层、第二栅极层、第三栅极层，第一信号线和第二信号线还可以位于增设的导电层，此外，第一信号线和第二信号线也可以位于同一导电层。It should be understood that in other exemplary embodiments, the first signal line and the second signal line may also be located in other conductive layers. For example, the first signal line may also be located in the first gate layer, the second gate layer, and the third gate layer in the display panel. The first signal line and the second signal line may also be located in an added conductive layer. In addition, the first signal line and the second signal line may also be located in the same conductive layer.

As shown in FIG2-20, the minimum distance between the orthographic projections of two adjacent second signal lines V2 on the substrate in the first direction X is S3, and the maximum distance between the orthographic projections of two adjacent second signal lines V2 on the substrate in the first direction X is S4, wherein (S4-S3)/S3 is greater than or equal to 0 and less than or equal to 0.2, for example, (S4-S3)/S3 can be equal to 0, 0.05, 0.1, 0.2, etc. When (S4-S3)/S3 is equal to 0, that is, the orthographic projections of the second signal lines V2 on the substrate are evenly spaced in the first direction X.

The second signal line V2 may include a plurality of second via contact portions Ht2 and a second extension portion Lt2, the orthographic projections of the plurality of second via contact portions Ht2 on the substrate are spaced apart along the second direction Y, the second extension portion Lt2 is connected to the second via contact portion Ht2, and the size of the orthographic projection of the second via contact portion Ht2 on the substrate in the first direction X is larger than the size of the orthographic projection of the second extension portion Lt2 on the substrate in the first direction X. The first via contact portion Ht1 and the second via contact portion Ht2 are arranged correspondingly, and the orthographic projection of the first via contact portion Ht1 on the base substrate and the orthographic projection of the corresponding second via contact portion Ht2 on the base substrate at least partially overlap.
如图2-20所示，所述第一过孔接触部Ht1可以包括第一实孔接触部Htr1和第一虚孔接触部Htd1，所述第二过孔接触部Ht2可以包括第二实孔接触部Htr2和第二虚孔接触部Htd2。所述第一实孔接触部Htr1和与其对应的所述第二实孔接触部Htr2通过过孔连接，即第一信号线H1和第二信号线V2可以通过第一实孔接触部Htr1和第二实孔接触部Htr2过孔连接。第一虚孔接触部Htd1和与其对应的所述第二虚孔接触部Htd2绝缘设置。第一虚孔接触部Htd1可以模拟第一实孔接触部Htr1的反光现象，第二虚孔接触部Htd2可以模拟第二实孔接触部Htr2的反光现象。从而第一虚孔接触部Htd1、第二虚孔接触部Htd2可以改善显示面板息屏下的暗影问题。此外，第一虚孔接触部Htd1可以模拟第一实孔接触部Htr1的寄生电容，第二虚孔接触部Htd2可以模拟第二实孔接触部Htr2的寄生电容，从而第一虚孔接触部Htd1、第二虚孔接触部Htd2可以提高显示面板的显示均一性。As shown in FIG. 2-20, the first via contact Ht1 may include a first real hole contact Htr1 and a first virtual hole contact Htd1, and the second via contact Ht2 may include a second real hole contact Htr2 and a second virtual hole contact Htd2. The first real hole contact Htr1 and the corresponding second real hole contact Htr2 are connected through vias, that is, the first signal line H1 and the second signal line V2 may be connected through the first real hole contact Htr1 and the second real hole contact Htr2 vias. The first virtual hole contact Htd1 and the corresponding second virtual hole contact Htd2 are insulated. The first virtual hole contact Htd1 can simulate the reflection phenomenon of the first real hole contact Htr1, and the second virtual hole contact Htd2 can simulate the reflection phenomenon of the second real hole contact Htr2. Therefore, the first virtual hole contact Htd1 and the second virtual hole contact Htd2 can improve the dark shadow problem of the display panel when the screen is off. In addition, the first virtual hole contact portion Htd1 can simulate the parasitic capacitance of the first real hole contact portion Htr1, and the second virtual hole contact portion Htd2 can simulate the parasitic capacitance of the second real hole contact portion Htr2, so that the first virtual hole contact portion Htd1 and the second virtual hole contact portion Htd2 can improve the display uniformity of the display panel.
本示例性实施例中，第一虚孔接触部Htd1和第二虚孔接触部Htd2在衬底基板上的正投影交叠。从而从反光角度出发，显示面板可以择一设置第一虚孔接触部Htd1或第二虚孔接触部Htd2。In this exemplary embodiment, the orthographic projections of the first virtual hole contact portion Htd1 and the second virtual hole contact portion Htd2 on the base substrate overlap, so that from the perspective of light reflection, the display panel can selectively set the first virtual hole contact portion Htd1 or the second virtual hole contact portion Htd2.
本示例性实施例中，如图2-20所示，相邻所述第一过孔接触部Ht1在所述衬底基板上的正投影在所述第一方向X上的最小距离为S5，相邻所述第一过孔接触部Ht1在所述衬底基板上的正投影在所述第一方向X上的最大距离为S6，其中，(S6-S5)/S5可以大于等于0且小于等于0.2，例如，(S6-S5)/S5可以等于0、0.05、0.1、0.2等。当(S6-S5)/S5等于0时，第一过孔接触部Ht1在衬底基板上的正投影在第一方向X上等间距分布。等间距分布的第一过孔接触部Ht1可以进一步改善显示面板息屏下的暗影问题。如图2-20所示，相邻所述第二过孔接触部Ht2在所述衬底基板上的正投影在所述第二方向Y上的最小距离为S7，相邻所述第二过孔接触部Ht2在所述衬底基板上的正投影在所述第二方向Y上的最大距离为S8，其中，(S8-S7)/S7大于等于0且小于等于0.2。例如，(S8-S7)/S7可以等于0、0.05、0.1、0.2等。当(S8-S7)/S7等于0时，第二过孔接触部Ht2在所述衬底基板上的正投影在所述第二方向Y上等间距分布，等间距分布的第二过孔接触部Ht2可以进一步改善显示面板息屏下的暗影问题。In this exemplary embodiment, as shown in FIG. 2-20, the minimum distance between the orthographic projections of adjacent first via contact portions Ht1 on the substrate in the first direction X is S5, and the maximum distance between the orthographic projections of adjacent first via contact portions Ht1 on the substrate in the first direction X is S6, wherein (S6-S5)/S5 may be greater than or equal to 0 and less than or equal to 0.2, for example, (S6-S5)/S5 may be equal to 0, 0.05, 0.1, 0.2, etc. When (S6-S5)/S5 is equal to 0, the orthographic projections of the first via contact portions Ht1 on the substrate are evenly spaced in the first direction X. The evenly spaced first via contact portions Ht1 can further improve the dark shadow problem of the display panel when the screen is off. As shown in FIG2-20, the minimum distance between the orthographic projections of adjacent second via contact portions Ht2 on the substrate in the second direction Y is S7, and the maximum distance between the orthographic projections of adjacent second via contact portions Ht2 on the substrate in the second direction Y is S8, wherein (S8-S7)/S7 is greater than or equal to 0 and less than or equal to 0.2. For example, (S8-S7)/S7 can be equal to 0, 0.05, 0.1, 0.2, etc. When (S8-S7)/S7 is equal to 0, the orthographic projections of the second via contact portions Ht2 on the substrate are evenly spaced in the second direction Y, and the evenly spaced second via contact portions Ht2 can further improve the shadow problem of the display panel when the screen is off.
本示例性实施例中，显示面板还包括像素驱动电路和发光单元，所述像素驱动电路连接所述发光单元的第一电极，所述显示面板还包括用于形成所述发光单元第一电极的电极层。如图24、25、26、27所示，图24为本公开显示面板另一种示例性实施例的结构版图，图25为图24中第一信号线所在导电层的结构版图，图26为图24中第二信号线所在导电层的结构版图，图27为图24中电极层的结构版图。电极层可以包括多个电极部，多个电极部中包括第一电极部R、第二电极部B、第三电极部G。第一电极部R可以用于形成红色发光单元的第一电极；第二电极部B可以用于形成蓝色发光单元的第一电极；第三电极部G可以用于形成绿色发光单元的第一电极。其中，该显示面板还包括包括位于电极层背离衬底基板一侧的像素定义层，像素定义层上形成有用于形成发光单元的像素开口。第一电极部R在衬底基板上的正投影和像素定义层上与其对应的像素开口在衬底基板上的正投影重合，第三电极部G在衬底基板上的正投影和与其对应的像素开口在衬底基板上的正投影重合，第二电极部B在衬底基板上的正投影和与其对应的像素开口在衬底基板上的正投影重合。In this exemplary embodiment, the display panel further includes a pixel driving circuit and a light-emitting unit, the pixel driving circuit is connected to the first electrode of the light-emitting unit, and the display panel further includes an electrode layer for forming the first electrode of the light-emitting unit. As shown in Figures 24, 25, 26, and 27, Figure 24 is a structural layout diagram of another exemplary embodiment of the display panel disclosed in the present disclosure, Figure 25 is a structural layout diagram of the conductive layer where the first signal line is located in Figure 24, Figure 26 is a structural layout diagram of the conductive layer where the second signal line is located in Figure 24, and Figure 27 is a structural layout diagram of the electrode layer in Figure 24. The electrode layer may include a plurality of electrode portions, including a first electrode portion R, a second electrode portion B, and a third electrode portion G. The first electrode portion R can be used to form a first electrode of a red light-emitting unit; the second electrode portion B can be used to form a first electrode of a blue light-emitting unit; and the third electrode portion G can be used to form a first electrode of a green light-emitting unit. Among them, the display panel also includes a pixel definition layer located on the side of the electrode layer away from the substrate, and a pixel opening for forming a light-emitting unit is formed on the pixel definition layer. The orthographic projection of the first electrode portion R on the substrate coincides with the orthographic projection of the corresponding pixel opening on the pixel definition layer on the substrate substrate, the orthographic projection of the third electrode portion G on the substrate coincides with the orthographic projection of the corresponding pixel opening on the substrate substrate, and the orthographic projection of the second electrode portion B on the substrate coincides with the orthographic projection of the corresponding pixel opening on the substrate substrate.
如图24-27所示，所述第一数据扇出线Fa1和所述第一模拟线Dm1之间断口D1在所述衬底基板上的正投影与所述电极部在所述衬底基板上的正投影不交叠；所述第二数据扇出线Fa2和所述第二模拟线Dm2之间断口D2在所述衬底基板上的正投影与所述电极部在所述衬底基板上的正投影不交叠。该设置可以提高电极部的平坦度，平坦度较高的电极部上可以形成平坦度较高的发光材料层，从而该设置提高显示面板显示的均一性。As shown in FIGS. 24-27, the orthographic projection of the break D1 between the first data fan-out line Fa1 and the first analog line Dm1 on the substrate does not overlap with the orthographic projection of the electrode portion on the substrate; the orthographic projection of the break D2 between the second data fan-out line Fa2 and the second analog line Dm2 on the substrate does not overlap with the orthographic projection of the electrode portion on the substrate. This arrangement can improve the flatness of the electrode portion, and a light-emitting material layer with higher flatness can be formed on the electrode portion with higher flatness, so that this arrangement improves the uniformity of display of the display panel.
本示例性实施例中，第一实孔接触部Htr1和第二实孔接触部Htr2通过过孔连接，第二实孔接触部Htr2在过孔位置会出现面向衬底基板的凹陷，第二实孔接触部Htr2在凹陷位置会出现较强的反光现象。然而，由于第一虚孔接触部Htd1和第二虚孔接触部Htd2并不连接，第二虚孔接触部Htd2较为平坦，第二虚孔接触部Htd2的反光较弱，第二虚孔接触部Htd2和第二实孔接触部Htr2不一致的反光能力容易导致显示面板息屏状态下出现暗影。In this exemplary embodiment, the first real hole contact portion Htr1 and the second real hole contact portion Htr2 are connected through a via hole, and the second real hole contact portion Htr2 will have a depression facing the substrate at the via hole position, and the second real hole contact portion Htr2 will have a strong reflection phenomenon at the depression position. However, since the first virtual hole contact portion Htd1 and the second virtual hole contact portion Htd2 are not connected, the second virtual hole contact portion Htd2 is relatively flat, and the reflection of the second virtual hole contact portion Htd2 is weak. The inconsistent reflection ability of the second virtual hole contact portion Htd2 and the second real hole contact portion Htr2 can easily cause a dark shadow to appear when the display panel is in the off state.
如图28所示，为图3所示显示面板沿虚线CC的部分剖视图。第一信号线位于第一源漏层，第二信号线位于第二源漏层，该显示面板还可以包括位于衬底基板90一侧的钝化层97、第一平坦层98，钝化层97位于第一源漏层和第二源漏层之间。第一平坦层98位于钝化层97和第二源漏层之间。第一平坦层98的厚度远大于钝化层97的厚度。本示例性实施例中，可以通过减小钝化层97和/或第一平坦层98的厚度减小第二实孔接触部Htr2在过孔位置处的凹陷深度，从而改善上述暗影问题。本示例性实施例中，第一平坦层98的厚度可以小于等于1.6um，例如，第一平坦层98的厚度可以为1.2um、1.3um、1.4um、1.5um、1.6um；钝化层97的厚度可以为1000埃到5000埃，例如，钝化层97的厚度可以为1000埃、2000埃、3000埃、4000埃、5000埃。As shown in FIG. 28 , it is a partial cross-sectional view of the display panel shown in FIG. 3 along the dotted line CC. The first signal line is located at the first source-drain layer, and the second signal line is located at the second source-drain layer. The display panel may further include a passivation layer 97 and a first flat layer 98 located on one side of the base substrate 90, and the passivation layer 97 is located between the first source-drain layer and the second source-drain layer. The first flat layer 98 is located between the passivation layer 97 and the second source-drain layer. The thickness of the first flat layer 98 is much greater than the thickness of the passivation layer 97. In this exemplary embodiment, the depth of the depression of the second real hole contact Htr2 at the via position can be reduced by reducing the thickness of the passivation layer 97 and/or the first flat layer 98, thereby improving the above-mentioned shadow problem. In this exemplary embodiment, the thickness of the first flat layer 98 may be less than or equal to 1.6um, for example, the thickness of the first flat layer 98 may be 1.2um, 1.3um, 1.4um, 1.5um, or 1.6um; the thickness of the passivation layer 97 may be 1000 angstroms to 5000 angstroms, for example, the thickness of the passivation layer 97 may be 1000 angstroms, 2000 angstroms, 3000 angstroms, 4000 angstroms, or 5000 angstroms.
如图29所示，为本公开显示面板另一种示例性实施例的结构示意图。该显示面板中的第一源漏层和第二源漏层之间可以仅设置第一平坦层98，该设置同样可以降低第二实孔接触部Htr2在过孔位置处的凹陷深度，从而改善上述暗影问题。As shown in Figure 29, it is a schematic diagram of the structure of another exemplary embodiment of the display panel of the present disclosure. In the display panel, only the first planar layer 98 can be arranged between the first source-drain layer and the second source-drain layer, and this arrangement can also reduce the depression depth of the second real hole contact portion Htr2 at the via hole position, thereby improving the above-mentioned shadow problem.
如图30所示，为本公开显示面板另一种示例性实施例的结构示意图。本示例性实施例中，第一平坦层98上形成有第一开孔H3，所述第一开孔H3在所述衬底基板上的正投影与所述第二虚孔接触部Htd2在所述衬底基板上的正投影至少部分交叠。该设置可以使得第二虚孔接触部Htd2形成面向衬底基板90的凹槽，从而通过增加第二虚孔接触部Htd2反光能力提高显示区反光的均一度。其中，第一开孔H3可以为贯穿第一平坦层98的开孔，也可以为没有贯穿第一平坦层98的盲孔。As shown in FIG30 , it is a schematic diagram of the structure of another exemplary embodiment of the display panel of the present disclosure. In this exemplary embodiment, a first opening H3 is formed on the first flat layer 98, and the orthographic projection of the first opening H3 on the base substrate overlaps at least partially with the orthographic projection of the second virtual hole contact portion Htd2 on the base substrate. This setting can make the second virtual hole contact portion Htd2 form a groove facing the base substrate 90, thereby improving the uniformity of the reflection of the display area by increasing the reflective ability of the second virtual hole contact portion Htd2. Among them, the first opening H3 can be an opening that penetrates the first flat layer 98, or it can be a blind hole that does not penetrate the first flat layer 98.
如图31所示，为本公开显示面板另一种示例性实施例的结构示意图。本示例性实施例中，所述钝化层97上形成有第二开孔H2，所述第二开孔H2在所述衬底基板上的正投影与所述第二虚孔接触部Htd2在所述衬底基板上的正投影至少部分交叠。该设置可以使得第二虚孔接触部Htd2形成面向衬底基板90凹陷的凹槽，从而通过增加第二虚孔接触部Htd2反光能力提高显示区反光的均一度。其中，第二开孔H2可以为贯穿钝化层97的开孔，也可以为没有贯穿钝化层97的盲孔。As shown in FIG. 31 , it is a schematic diagram of the structure of another exemplary embodiment of the display panel disclosed in the present invention. In this exemplary embodiment, a second opening H2 is formed on the passivation layer 97, and the orthographic projection of the second opening H2 on the base substrate overlaps at least partially with the orthographic projection of the second virtual hole contact portion Htd2 on the base substrate. This setting can make the second virtual hole contact portion Htd2 form a groove that is recessed toward the base substrate 90, thereby improving the uniformity of the reflection of the display area by increasing the reflective ability of the second virtual hole contact portion Htd2. Among them, the second opening H2 can be an opening that penetrates the passivation layer 97, or it can be a blind hole that does not penetrate the passivation layer 97.
本示例性实施例中，由于第一过孔接触部Ht1和第二过孔接触部Ht2在衬底基板上的正投影交叠，从而第二过孔接触部Ht2相比其他位置具有较高的凸起。同时，由于第二实孔接触部Htr2的局部区域具有凹槽，为了提高电极部的平坦度，如图24所示，本示例性实施例中，所述第一过孔接触部Ht1在所述衬底基板上的正投影和所述电极部在所述衬底基板上的正投影不交叠；所述第二过孔接触部Ht2在所述衬底基板上的正投影和所述电极部在所述衬底基板上的正投影不交叠。In this exemplary embodiment, since the orthographic projections of the first via contact portion Ht1 and the second via contact portion Ht2 on the base substrate overlap, the second via contact portion Ht2 has a higher protrusion than other positions. At the same time, since a local area of the second via contact portion Htr2 has a groove, in order to improve the flatness of the electrode portion, as shown in FIG. 24 , in this exemplary embodiment, the orthographic projection of the first via contact portion Ht1 on the base substrate and the orthographic projection of the electrode portion on the base substrate do not overlap; the orthographic projection of the second via contact portion Ht2 on the base substrate and the orthographic projection of the electrode portion on the base substrate do not overlap.

At least part of the structure of the second via contact portion Ht2 and the fourth extension portion Lt4 are arranged relative to each other in the first direction X, and the size of the orthographic projection of the fourth extension portion Lt4 on the substrate and the orthographic projection of the second extension portion Lt2 on the substrate in the first direction X is larger than the size of the orthographic projection of the third extension portion Lt3 on the substrate and the orthographic projection of the second extension portion Lt2 on the substrate in the first direction X, and the size of the orthographic projection of the fourth extension portion Lt4 on the substrate and the orthographic projection of the second extension portion Lt2 on the substrate in the first direction X is larger than the size of the orthographic projection of the fifth extension portion Lt5 on the substrate and the orthographic projection of the second extension portion Lt2 on the substrate in the first direction X. Among them, the structure A and the structure B are arranged relative to each other in the first direction, which can be understood as that the area covered by the infinite movement of the orthographic projection of the structure A on the substrate in the first direction and the area covered by the infinite movement of the orthographic projection of the structure B on the substrate in the first direction overlap. This arrangement can make the second via contact portion Ht2 have sufficient arrangement space.
